Chapter 5 and 6

Vocab Words

Octet Rule A concept of chemical bonding theory that is based on the assumption that atoms tend to have either empty valence shell of eight electrons
Ion An atom, radical, or molecule that has gained or lost one or more electrons and has a negative or positve charge
Cation An ion that has a positive charge
Anion An ion that has a negative charge
Salt An ionic compound that forms when a metal atom or a positive radical replaces the hydrogen of an acid
Lattice Energy The energy associated with constructing a crystal lattice relative to the energy of all constituent atoms separated by infinate distances
Crystal Lattice The regular pattern in which a crystal is arranged
Unit Cell The smallest portion of a crystal lattice that shows the three-dimensional pattern of the entire lattice
Polyatomic Ion An ion made of two or more atoms
Covalent Bond A bond formed when atoms share one or more pairs of electrons
Molecular Orbital The region of high probability that is occupied by an individual electron as it travels wth a wavelike motion in the three-dimentional space around one of two or more associated nuceli
Bond Length The distance between two bonded atoms at their minimum potential energy; the average distance between the nuclei of two bonded atoms
Bond Energy The energey required to break the bonds in 1 mol of a chemical compound
Nonpolar Covalent bond A covalent bond in which the bonding electrons are equally attracted to both bonded atoms
Polar Covalent Bond A covalent bond in which a shared pair of electrons is held more closely by one of the atoms
Dipole A molecule or part of a molecule that contains both positively and negativly charged regions
Valence Electron An electron that is found in the outermost shell of an atom and that determines the atoms chemical properties
Lewis Structure A structural formula in which electrons are represented by dots; dot pairs or dashes detween two atomic symbols represent pairs in covalent bonds
Unshared Pairs A nonbonding pair of electrons in the valence shell of an atom; also called the lone pair
Single Bond A covalent bond in which two atoms share one pair of electrons
Double Bond A covalent bond in which two atoms share two pairs of electrons
Triple Bond A covalent bond in which two atoms share three pairs of electrons
Resonance Structure in chemistry, any one of two or more possible confugratios of the same compound that have identical geometry but different arrangements of electrons
Valence Shell Electron Pair Repulsion (VSEPR) Theory A thoeory that predicts some molecular shapes based on the idea that pairs of valence electrons surrounding and atom repel each other

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
